To all whom 'irl may conm-nin v Be 1t known that l, PETER l. LNGLYKKE,

'a citizen ot the `United States, residing at.

Chicago, in the county oi Cook and State of illinois, have inventedcertain new and useful Improvements in Spring Structures for Cushions,of which the following is a spe'cication.

The invent-ion relates to improvements in spring structures for cushionsand the like.

(.)ne of the. objects of the inventio-n is to generally improve springstructures for cushions to render them more uniformly elastic orresilient and to provide means to unfailingly maintain the helical'springs thereof in upright positions or to so arrange .them that theywill always return to their .sewing machines, there being practically nohand labor required in their production.

Other, further and more particular objects of my invention will readilyappear from a consideration'cf the following description When taken inconnection with the accompanying drawing, wherein v broken away showinga spring in one 'of the- Figure 1 shows a plan View of ay completecushion foundation with a part of the o-uter receptacle broken away toshow a series ot' spring containers therein.

Fig. 2 is a. section taken on line 2-2 of Fig. 1.

Fig. 3 is a section taken on line 3 3 of Fig. 1. Y

Fig. 4 is an elevation of one of the spring containing pocket structureswith part pockets.

, ln all the views the-same reference characters are employed to show4like parts.

i. ,The springs are of uniform diameter of the helical type suchl as areused in structures of this general character. Each spring is containedin a separate pocket such as shown at 6, in Fig. 4 and a. series of.spring pockets 6 are formed in a single container Y and the Acontainersfilled With springs 'are placediY in relatively long pockets fabricreceptacles 9.

The spring containers 7 areeach made, preferably, of a single piece offabric, doubled over, as at 10, into a. sort of bag formation, thenthetwo side members 411 and 12 are seWed together forming vertical seams13, spaced apart to form the pockets 6 to contain the springs 5, afterthe springs have 8 in the been plalted, each in a separate pocket.Thenthe tivo4 upper edges of the side members, 11 and 12, are sewedtogether, as at 14, to close the pockets.

A'series of structures 7 are no-W lto he placed in relatively elongatedpockets 8 in vthe receptacle 9 as shown to the left in Fig.

2 and in Fig. 1. rlhe receptacle 9consists ol an upper sheet 15 and alower sheet 16. Strips 17 of proper height and length are firststitchedv to one of the sheets 15 or 16,. as at 18, in spaced-apartrelation, then the other longitudinal edges of the strips 17 areproperly spaced apart and stitched to the other sheet, as at 19. Thiscan conveniently be done by heginningat the left and stitching the seamsto the sheet in regular sequence. This forms the relatively long pocketsfor the spring containers. `After this has been done, then the edgestrip 2O is seived -to the sheets 15 and 16, as at 21 and 22,respectively. One of the end strips 2O is left otf until the containers7 have all been placed in the pockets 8, then the end strip isstitchedin place and the elongated pockets properly closed. v 'While Ivhaveherein shown a single embodiment of my structure for the purpose ofclear disclosure, it lvvill be `manifest that changes, may be madetherein Within the scope of the appended claim.

Having-described my invention what I claim as newv and desire to secureby Letters A mattress structure having a plurality oi ,inner coverings,each vto contains series of separated coil springs', each coveringiraitL comprising a sling-le piece of a-hric folded@ in U- shapeformation, said folds providing twove-rtic'al porale side Walls and Lbase wall, he latter as wide as the spring to be oontninod therein, saidinner covering dvded, at intervals, by Vertical .seams to pro- Vide aseries of closed cylndrca pockets constituting. .a unit and a coil sp'ngn each pocket and .an outer covering comprising a,

series of parallel stalls, each stall remngu! fabric' walls betweonsprings of/ adjacent units.
